Nodejs没有为office插件启动web服务

Question

Recently I jumped into creating office web add-ins and have created a couple using visual studio. But now, I have to change to creating add-in using NodeJS. I followed the official Microsoft instruction for the Yeoman generator and the installation works fine until I run

npm start

This logs.

C:\Users\***\source\secondapp>npm start

> office-addin-taskpane-js@0.0.1 start
> office-addin-debugging start manifest.xml

Debugging is being started...
App type: desktop
Enabled debugging for add-in b56ba8a6-675d-44bd-8182-0822410ef349. Debug method: 0
Sideloading the Office Add-in...
Debugging started.

As you can the web service fails to start. Without giving any errors.

Answer 1

I have guite same situation right now.. just word is open but not started webpack. I have to start it manually

npm run dev-server

than I was able to open my addin in MSWord..

I use to work with it about year and half just by

npm start

but perhaps after updatin node to node 15.14.. its stops working.. Give a try to start first dev server and than open office
